Abstract: An automated logic circuit design system uses a common database to store design data at different states of the design process, including data-flow graphs, netlists and layout descriptions. In this way, the need to translate circuit descriptions between tools is eliminated, thus leading to increased speed, flexibility and integration. The common database includes entities, models, cells, pins, busses and nets. Physical design data is available by storing the cells in a KD tree. This allows queries on cells in the netlist located in the layout within arbitrary areas.

Title: A manufacturing method for a glass substrate having a phosphor layer used as a color cathode ray tube front panel and a color cathode ray tube manufacturing method
Inventor: ONISHI RYOJI
IPC: H01J9/227
Filed: 2000-06-16
Granted: 2001-11-21
Abstract: A glass substrate manufacturing method and a color cathode ray tube manufacturing method manufactures a front substrate on which a phosphor layer is formed. In an application process a phosphor slurry of one color is applied onto an inner surface of a glass substrate on which a phosphor pattern in at least one color has already been formed. Then, in a spreading process, the glass substrate is rotated about an axis located at the approximate center of the inner surface to make the phosphor slurry spread out over its inner surface. Following this, in a draining process the glass substrate is tilted to a first tilt angle of more than 90 DEG to drain excess slurry off the inner surface of the glass substrate, a tilt angle being formed between a vertical axis and an axis orthogonal to an outer surface of the glass substrate. In a spinning process the glass substrate is returned to a second tilt angle smaller than the first tilt angle, and rotated.

Filed: 2000-11-15
Granted: 2003-11-11
Abstract: A plasma processing system that includes a plasma processing chamber that provides enhanced control over an etch process is disclosed. The plasma processing chamber is connected to a gas flow system. The gas flow system can be employed to control the release of gases into different regions within the plasma processing chamber. In addition, the volume of the released gas, e.g., the flow rate of the gas, can be adjusted by a gas flow control mechanism. In this manner, both the position and the amount of the gas that is delivered to the plasma processing chamber can be controlled. The ability to adjust the position and the amount of gas that is released into the plasma processing chamber provides for a better control over the distribution of the neutral components. This in turn enhances control over the etching process.
